The DCprox are not over ear, they are on ear. The don't have any more clamping force than the cheap issued telex. Probably not as quiet as Bose. The noise isn't bad on the bus at all. However, when we wear headsets is when it is usually loudest and busiest (takeoff and land) where I work. I managed without them for a couple months, but was frustrated with the headsets and being able to hear the comms clearly. We do use ics when the headsets are on after push. I am in the minority as far as those with a purchased headaet. I gave my story and why I bought them in case the guy finds himself in a similar situation. 650 is a bit is cash, I'll agree and the Bose are nearly a grand (if you want over ear cups).
